DIE-PRESS.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed November 9, 1909. Serial No. 527,098.

To all whom it may concern:

Be it known that I, ALFRED W. Roovsns, a citizen of the United States, residing at I Brooklyn, in the county of Kings and State of New.York, have invented certain new and useful Improvements in Die-Presses, of

which the following is a specification.

This invention relates to hand presses adapted to impress seals, monograms, or

other designs upon .paper or similar materia-l.

The invention resides in the form and construction of the parts whereby the press is constructed completely of stampings. It

is consequently capable of cheap manufacture without sacrifice of strength or accuracy. v

A press embodying the features of'i'ny invention is illustrated in the accompanying drawings, in which Figure 1 is-a longitudinal section of the assembled device, the plane of section .being taken upon the center line; Fig. 2 is a perspective view of the cam lever removed from the device; Fig. '3 is a' perspective viewofv the frame; Fig; 4 is a perspective view of 'the combined diecarrien and spring; Fig.

. 5 is a perspective view of the male die,

showing it in the form it assumes after being attached to the diecarrier;' Fig. 6 is a detail view of one die carrier, showing the female die impressed directly therein; and Fig. 7 is adeta il view of the male die and its carrier, parts of the former being broken away to show the 1atter i As clearl illustrated in Figs. 1 and 3,

- the frame or the press consists of a sheet i cated each side late.

metal stamping 1, symmetrical with respect to a line and bent upon itself along this line, so that the two side portions form two parallel side platesfspaced from each other a convenient distance preferably about a quarter of aninch'.

The side plates; are narrowed or cut away.

at the rear portion, so as to form a short projection 2, adapted to serve as a handle, and this portion 2 is forced into a rounded or spherical form, as at 3, to give a more com ortable. ip,tothe hand of the operatorn Eitten ing from t-he forward end of the frame are tapering slots 4, similarly lo- These slots are for the reception of t e combined die carriers and spring, as will be described. The two side plates are further provided with similarly located holes 5, 6, and 7, adapted to and the two side portionsof the stamping at the end adjacent the rivet are shaped to form cam surfaces 11. A filler block 12, of

similar contour, is' inserted between these two cam surfaces 11, and is held in place by the rivet 8. The thickness of the lever,

measured through the cam surfaces 11, is such that. the lever fits snugly between the side plates of the frame 1. A rivet 13 is inserted in the holes fiwtoy strengthen the frame, and serve as a limit stop for the cam lever, while a third rivet 14 passes through the holes 7 and serves to hold in place the combined die carrier and spring. Thisconsists of a stamping comprising two disk like portions 15 a-nd16, connected by a narrower straight portion 17, bent upon itself at its middle, so as to bring the portions 15 and 16, which are the die carriers, adjacent 'to each other, as shown in Figs. 1 and 4.

The bend in the portion 17 is made with a loop or goose neck 18. This loop 18 surrounds the rivet 14. and thereby holds the diecarrier and spring in its position in the frame 1, and also furnishes greater resiliency.

As clearly shown in Fig. 1, the die carriers 15 and 16 lie in theslots 4, beneath the team 11, so as to be forced together by the rotation of this cam. The portion 17 extends rearwardly and fits closely between the side plates .of the frame 1, thus preventing lateral motion of the dies, while the rivet- 14 prevents longitudinal motion.

The dies are thus'constral'ned' to move di-' rectly toward and from-each other in an approximately circular path. The femaledie carrier 15' has the/die impressed di-' rectly in its surface. The male die, however, is pressed in asheet; metal stamping 19, having flanges 20 (see Fig. 5), spun around the periphery'of the die carrier 16.

By adopting this construction I am enabled to form both dies of stampings.

-From the foregoing description, the operation of the device will be obvious.

By stamping both the dies, I am enabled greatly-to cheapen the cost of manufacture, and it is alsoobvious that the die carriers, frame, and handle may each be stamped out at one operation, the holes, slots, etc., being punched out at the same time that the blank is made. It is then onlynecessary to press them'to form and assemble the various parts.

In mounting the male die upon its carrier 16 I find the following procedure advantageous to secure accurate register of r the dies. After the female die is impressed in the-carrier 15 the twp carriers arebrought into. their final ,positions as shown 20 in Fig. 4 by forming the bend 18.. "The male die 19 .is then placed on'the carrier than the carrier 15 so that the finished malef i' it to the female die.

securing accurate flanges vbeing not yet bent down. The two die carriers are then forced together so that the male andfemale dies are forcedtogether in accurate re ister and while the dies are so heldthe down upon theback of the carrier 16, thus ositionin' of the dies. The carrier 16 may be made s ightly smaller die shall have the same outside diameter as process of adjustaving' thus described my invention, what I claim is 1. The combination of actuating means;

cooperating die faces peach formed in'sheet metal; a connecting guiding member formed 'integral ith. one die and attached to the other die, the said guiding member having 5 a narrowed resilient portion bent upon 'itself. to form a'loop and to'bring'the dies into'proximity; and a pin engaging said At this stageit is cup-shaped,. the.

anges 20 are spunloop to retain the guiding member in proper relation with the actuatin means.

2. A die press comprising a rame; ac-

tuatiug means mounted therein; a pair of dies actuated by said means; a resilient itself to form side plates; a cam lever pivloted in said frame; a pair of die carriers mounted in the slots of the frame so as to .be actuated by the cam lever a connecting resilient portion formed integrally with said carrier and guided by the side plates of the frame; a retaining pin in the frame engaging said resilient connecting portion;

a die impressed in one'carrier; and a sec- 0nd die formed in sheet material and at tached to the other carrier.

. 4.: In a die press; the combination of a frame consisting of a piece of sheet material provided with two slots and bent upon itself to form side plates spaced apart and to bring said slots into alinement; a die actuatmg lever pivoted in the frame; a re silient die carrier consisting of two head portions connected by a narrowed portion bent upon itself to-bring the head portions into proximity, the die carrier being inserted in the frame with its narrowed portion confined between the side plates and the head portions in the slots'and beneath the actuating lever; a pin engaging thedie carrier to hold it in position; and die faces carried by the head portions of the carrler.

In testimony whereof I have signed my name to this specification in the presence of two "subscribing witnesses.
